Reaction Steps
100 mg (0.45 mmol) 1,3-Dimethyl-2,6-dioxo-2,3,6,7-tetrahydro-1H-purine-8-carboxylic acid were dissolved in 5 mL DMF. Subsequently 227 μl (1.35 mmol) DIPEA and 186.5 mg (0.495 mmol) HATU were added. After 1 h 105.6 mg (0.495 mmol) 1-isopropyl-piperidine-4-ylamine-dihydrochloride and 227 μl (1.35 mmol) DIPEA were added and the resulting mixture was stirred at room temperature for 4 h. The reaction mixture was concentrated and purified by preparative RP-HPLC (CH3CN/H2O gradient+0.05% formic acid) to give 1,3-dimethyl-2,6-dioxo-2,3,6,7-tetrahydro-1H-purine-8-carboxylic acid (1-isopropyl-piperidin-4-yl)-amide as its formiate.
